As a starter the value of that car is dropping like a rock in a lake with no bottom. The real trade in value is between $25000.00 and $31000.00 at best. I was lucky to buy it with a POC on it otherwise I would have left my wallet at the dealer. Lots of squeaking and annoying noise coming from the chassis. Lots of problem with the electronic, seat wont recline and suddenly they do, the lighting. The air ride suspension is nice but unreliable and can collapse at any time. They had to replace the whole rear end at 48000 miles. Please stay away from Mercedes benz and leave MB where they deserve to be, in bankruptcy.
